    Abstract: A node of a storage service is selected as a coordinator of a distributed transaction involving multiple page-level modifications. The coordinator identifies other nodes as members of a node chain collectively storing physical data pages at which proposed modifications are to be performed, including a decider node responsible for a decision to commit the transaction. The coordinator generates a transaction preparation message comprising a representation of an order of respective commit decisions associated with the proposed modifications, and transmits the message to a selected node of the chain for a sequential propagation along the chain. Each chain node performs a local commit analysis for its changes and stores a record of its intent to commit. If a decision to commit is reached at the decider, the proposed modifications are completed.

    Abstract: At a particular node of a storage service to which connections have been established on behalf of one or more clients, respective workload indicators are collected from a set of peer nodes of the storage service. A determination is made at the particular node that (a) a local workload metric exceeds a connection rebalancing threshold, and (b) a peer capacity availability criterion has been met. The peer capacity availability criterion may be determined from the respective workload indicators. In response to the determination, a particular client connection is closed.

    Abstract: Methods and apparatus for intelligent cache eviction at storage gateways are disclosed. A system comprises computing devices configured to determine whether the number of free chunks of storage at a storage appliance for caching portions of a storage object is below a threshold value. If the number is below the threshold, the computing devices identify an eviction set of chunks to be freed, and generate a respective new instance identifier for each chunk of the eviction set. The identifier of a given chunk may be used to determine a validity of a block of the chunk. The devices store, within metadata storage of the appliance, the new instance identifiers of the eviction set, and indicate that the chunks of the eviction set are available for caching data of the storage object.

    Abstract: A set of techniques is described for monitoring and analyzing crashes and other malfunctions in a multi-tenant computing environment (e.g. cloud computing environment). The computing environment may host many applications that are executed on different computing resource combinations. The combinations may include varying types and versions of hardware or software resources. A monitoring service is deployed to gather statistical data about the failures occurring in the computing environment. The statistical data is then analyzed to identify abnormally high failure patterns. The failure patterns may be associated with particular computing resource combinations being used to execute particular types of applications. Based on these failure patterns, suggestions can be issued to a user to execute the application using a different computing resource combination. Alternatively, the failure patterns may be used to modify or update the various resources in order to correct the potential malfunctions caused by the resource.

    Abstract: Various embodiments disclosed herein including systems and methods for improving allocation of computing resources in a virtual machine (VM) environment. Embodiments maintain data relating to how VM image data is stored in storage devices and loaded into volatile memory such as random access memory (RAM). The data is then used to identify common content in the volatile memory that can be shared across VM instances. In some embodiments, multiple VM instances can share at least a portion of a single common VM image loaded into a shared volatile memory.

    Abstract: A client request, formatted in accordance with a file system interface, is received at an access subsystem of a distributed multi-tenant storage service. After the request is authenticated at the access subsystem, an atomic metadata operation comprising a group of file system metadata modifications is initiated, including a first metadata modification at a first node of a metadata subsystem of the storage service and a second metadata modification at a second node of the metadata subsystem. A plurality of replicas of at least one data modification corresponding to the request are saved at respective storage nodes of the service.

    Abstract: A request for a session identifier for a particular client is transmitted from an access subsystem of a storage service to a metadata subsystem of the service. A session identifier based on a persistent session storage location at which metadata of the client session are stored is received at the access subsystem. The session identifier is cached at the access subsystem prior to its transmission to the client. A lock state indicator generated by the metadata subsystem in response to a particular request from the client during the client session may also be cached at the access subsystem. Subsequent storage requests from the client during the session may be handled by the access subsystem using the cached session identifier and lock state indicator.
